Steve Ransom pointed me towards this video of a grade 1 teacher and how she uses blogs and wikis in her classroom. There is also some parent and student commentary. Her advice is to start small, with a blog for your classroom, and let yourself grow with it.
I’d like to hear her principal’s perspective as well!
(Oh, and I certainly hope she doesn’t work in this superintendent’s district. If she does she may need to watch out.)
